Debunking Microchip XLP low power claims and others(how Renesas K0R Ultra-Low Power MCU stacks up)


Low Power MCU claims

TI advertises they have the “World’s lowest power MCU” with MSP430 family!

Microchip claims to have lowest standby currents in “Deep-Sleep” modes – nanoWatt, XLP technology!

Now Silicon Labs claims to beat TI and Microchip for title of“World’s lowest power MCU” with new F900 low power 8-bit MCU series.

ST Micro, Energy Micro, and EM Electronics have Ultra-low Power MCU families heavily promoted

Hmm…. but Renesas Electronics has Ultra-low power MCU families with lower operating currents, and higher performance than most 8bit and 16bit competitors, including TI MSP430!

What does the Renesas spec sheet data say?


Debunking Microchip nanoWatt XLP Technology Claims

Benefits of nanoWatt XLP™ Technology include:■ Sleep / Power-down current down to 20 nA■ Brown-out Reset down to 45 nA ■ Watch-dog Timer down to 400 nA ■ Real-time Clock/Calendar down to 500 nA

•Mismatch in operation notes:•Coin cell batteries have a useful operating voltage range = 3.2V max to 2.4V min•Not realistic: 1mSEC out of 60SEC run time = 1/60000! (8.8minutes/year)

•Microchip battery life at higher duty cycles much worse than TI, Renesas,since active mode currents are 3x-5x that of TI and Reneas @ equivalent dmips!

From Microchip XLP website last year:

(assuming 1.8V operation, which is not practical or useable)

Main Point:•Don’t take allthe competitor’sLow power MCUClaims at Face Value

K0R: Internal Voltage Regulator Advantage

Internal core LDO voltage regulator minmizes IDD current drain at higher VDD

•Vreg = 2.4V Normal Operation•Vreg = 1.8V Low Power Mode

Functions/Peripherals attached to I/O pins

- Usually have current drains that rise proportionally to supply

Renesas K0R/Kx3-L, K0R/Lx3 Advantage: Internal LDO voltage regulator minimizes Core CPU and Aux. Peripheral Current drain. (at Maximum Performance)

Main Point:• Internal 2.4V LDO Voltage regulator helps minimize current drain, by keeping CPU @ constant voltage

Flash Security & Self-Programming: Safe, but Flexible

Data to be self-programmed can be obtained through any source available to the microcontroller under direct user control.

The flash memory can be separated into a boot area and program area, allowing manipulation of one without affecting the other

Each area is composed of multiple fixed-size blocks that can be manipulated independently.

Microchip with and without Internalcore voltage regulator (examples)

Microchip 8bit (without internal regulator):

– PIC16F1937– PIC16F917– PIC18F14K22– PIC18F14K50

8bit (with internal regulator):– PIC18F46J11– PIC18F46J50– PIC18F85J90 (LCD)

Microchip 16bit (without internal regulator):

– PIC24F04KA201– PIC24F16KA102

16bit (with internal regulator):– PIC24FJ64GA004– PIC24FJ256GA110

Look for “J” in part number:indicates internal Voltage Regulator version

Microchip MCUs without internal Voltage Regulator tout the very lowest Standby

currents at 20nA or 100nA typical @25C, 1.8V (0.3uA-1uA max @25C. 3V).

However operating currents suffer as VDD =2.7V-3.6V (3x-16x Renesas MCU)

Microchip MCUs with internal Voltage Regulator have average Standbycurrents at 0.3uA -1.5uA typical

@25C, 1.8V (1uA-10uA max @25C, 3V). And operating currents suffer

as VDD =2.7V-3.6V (1.6x-10x Renesas MCU)


TI MSP430 with and without Internalcore voltage regulator

TI MSP430 families 16bit (without internal regulator):

– MSP430F1xx/1xxx 8MHZ GP Series– MSP430F2xx/2xxx 16MHZ GP Series– MSP430F4xx/4xxx 16MHZ GP Series

16bit (with internal regulator)– MSP430F54xx/55xx 18/25MHZ GP Series

TI MSP430 MCUs without internal Voltage Regulator tout good Standby

currents at 20nA or 100nA typical @25C, 1.8V (0.3uA-1uA max @25C. 3V). However, max CPU perfomance suffers as VDD <3.3V (Renesas MCU: Full CPUPerformance over VDD = +2.7V – 5.5V)

TI MSP430F5xxx MCUs with internal Voltage Regulator have high Standby

currents at typical/max@+25C and @+85C

And operating currents are much higherthan Renesas 16bit MCU at the same clock

System Power Challenges for Battery-operated Instruments

Typical ultra-low-power system has short periods of high activity followed by long periods of low or no activity

Application example: handheld blood glucose meter

MCU requirements for ultra-low-power systems Processing capability to meet system throughput demands Efficient power utilization in all operating modes to enable long battery life

15 sec@8mA

180 sec@500uA

Total current = 1mA-SEC + 9mA-SEC + 120mA-SEC + 90mA-SEC = 220 mA-SEC (average per reading)

At 5 average readings per day, equates to 1100mA-SEC per day (3600 sec x 24 hrs = 86,400 sec per day)

Amount of time in standby = 86,400 – [(1 + 30 + 15 + 180 sec) x 5] = 85,370 sec/day

Assuming 1uA in standby, daily current budget = (85,370 sec x 1ua) + (1130 mA-SEC) = 1215.4 mA-SEC

Approximate life = (220mA-hr x 3600 sec/hr)/1215.4 mA-SEC/day = 651 days

Check to see if CR2032,220mA-hr capacity meetsapplication target time!
